1.1 Introduction ZGF DC high voltage generator is DC high voltage power supply equipment. it have functions of switch on protection under 0 voltage,over voltage and over current protection. They are high stability and reliability. ZGF is easy to operate , small in size and light in weight. 1.2 Function DC high voltage test for the power supply department, for example: DC HV withstand and leakage current test in power cables, the conductance current and 1mA reference voltage of magnetic blow out arrester and zinc oxide arrester test. Using as power supply of laser, also electrostatic painting and twine and so on. Other place required DC high voltage. 1.3 Major parameters Model Item ZGF-60/2 ZGF-120/2 ZGF-120/5 ZGF-200/2 ZGF-300/2/3 ZGF- 200/400/2 Output Voltage 60kV 120kV 120KV 200kV 300kV 200 / 400kV Output Current 2mA 2mA 5mA 2mA 2 mA/3mA 4 mA/ 2mA Output Power 120W 240W 600W 400W 600W/900W 800W Double voltage unit size 145×500(mm) 145×800 (mm) 140×800 (mm) 145×1000(mm) 145×1300(m m) 145×1200 Operating unit size 360×260×245(mm)(L×W×H) Total weight 10kg 15kg 17kg 20kg 25kg 40kg Ripple coefficient <0.5%
